Yep, I have it too! And, it does seem to be strange how it occurs. Sometimes, I get it when it really is not that cold, but sort of that difference between you are still warm and it is just starting to get cold. I will get it when I ride my bike downhill (which is sort of obvious, cold and wind-chill) and when I hike. When I hike it seems like it doesn't have to be that cold. Maybe it has something to do with the blood all going to the legs to keep them going or something? Anyway, it is manageable so far for me. I don't get it too often. But, I knew a lady who could hardly ride in the San Francisco Bay area in the winter cause it was so bad (and SF winters are not that bad). She would use those glove warmers all the time.
